Input to LaTeX

Space characters separate words. Two space characters in a row are
equivalent to a single space character. The end of line is also
equivalent to a space character. (However, a percent sign,
%, can end a line without
generating a space character.) Generally, space characters at the beginning
of a line are ignored.

An empty or blank line between two lines of text defines
a new paragraph.
Two blank lines are equivalent to one.

LaTex Commands

The second case is case-sensitive;
\Gamma is different from
\gamma.
These commands are terminated by a nonletter, i.e., a blank, a number,
a punctuation mark or special character.

Commands may have mandatory arguments, which are input in braces
({}).
They may also have optional arguments, which are input in square brackets
([]).

For commands which produce text a trailing blank may be interpreted as the
end of the command, which does not automatically create a space, so
you may have to do something to create an
interword space after this text.
